T 0 all whom it may concern.

Be it known that I, ELLIS W. TEST, a citizen of the United States, and resident of Michigan City, county of Laporte, and State of Indiana, have invented certain new and useful Improvements in Sheet-Metal Car Ends, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The lnvention relates to car ends formed of .sheet metal plates ora single plate for cars of the gondola type, the plate being pressed to orm corrugations. The improvement appertains to the arrangement or configuration of the corrugations and the in vention consists of a structure such as is hereinafter described and as lllustrated 1n theaccompanying drawings in which- Fig. 1 is detail side elevation of the body ofa box car; I

Fig. 2 is an end elevation thereof;

Fig.3 is a detail section on the .line' 3-3 of Fig. 2,-and

Fi 4 is a of Flg'. 2.

' In the drawings there is shown the-body 10 of a box car andbecauseof the height of the car the end is formed of two plates 11,

12, which are of substantiall the same form and hence, as tothe main eatures but one need be described. Each of these plates is provided with side marginal flanges '13, 14, overlapping the corner posts of the car and to which they may be suitably secured.

, The central portion of the plate, as 12, is bulged outwardly, as shown at 1'5, and this distortion of the. plate preferably takes an oval form, the longer axis of the oval being horizontal. 7

Intermediate of the ends of the portion 15 and the side margins of the plate the latter is distorted by a depression inward, as shown at 16, this depression extending along the upper and lower margins of the oval for a. considerable distance and hence taking substantially a U shape. Between the depressions 16 and the margins of the plate the latter remains in its original plane.

The lower margin of the upper plate overlaps the upper margin of the lower plate and the two plates are secured together by a series of rivets 17. The upper margin of the detail section on the linen-41 lower plate may be bent or flanged inwardly, as shown at 18, this flange not only stifl'ening the end of the car but affording means for attaching to the end a nailing stringer 19 to which a lining 20 for the car end may be secured, thereby avoiding the necessity for perforating the sheet metal plates for the accommodation of attaching bolts and obviating thedanger of leaky bolt holes- The described arrangement of the corrugations secures great strength to resist the pressure of shifting lading without materially increasing the length of the car. The central portion of the plate being bulged outwardly, the deflection from the plane of the platebeing in all directions, an arch is 'formed and outward pressure is resisted largely by 1 the tensile strength of the metal, the lines of resistance being distributed throughout the entire area of the bulge.

The inward depressions around the ends of the ovalbulge shorten the arch .and increase its strength. They also add to the strength of-the p ate in that they constitute vertical corrugations.

The particular configuration of the distortions of the centralportion of the plate may be varied without departing from the scope of the invention, which will include any form in which the plate has a central bulge, surrounded at least in part by depressions secured by pressing the plate in the opposite direction from its original plane.

I claim as my invention:

1. A car "end comprising a sheet metal plate having flat marginal portions, a central outward bulge, and end depressions bordering the bulge and merging into the central outward bulge and the flat marginal portions. I

2. A car end comprising a sheet metal plate having fiat marginal portions, inward depressions across the plate adjacent the marginal portions and a central outward bulge merging into the depressions.

3. A car end comprising a sheet metal plate having flat marginal portions, a central outward bulge oval in' form, and inward depressions bordering and merging into the ends and portions of the sides of the oval.

4. A car end comprising a sheet metal plate having flat marginal portions, a central outward bulge, and inward depressions bordering and merging into the ends and of substantially U-shape bordering and portions of the sides of the central bulge. mergin into the ends and portions of the 6. A car end comprising a sheet metal 10 sideso the central bulge. plate having flat marginal portions, a cen 5 5. A car end comprising a sheet metal tral outward 10111 e, and inward depressions plate having flat marginal portions, a cenin said flat marginal portions. tral outward bulge. and inward depressions ELLIS W.
